With the battle over across the first installment of across-the-board spending cuts all but over, Senate Budget Committee Chairman Patty Murray (D., Wash.) Friday sent a memo to fellow Democrats girding for the next battle, launching a pre-emptive attack on House Republicans’ budget for 2014.

Noting that House Budget Committee Paul Ryan (R., Wis.) has promised to write a budget that would eliminate the annual deficit in 10 years without raising taxes or cutting defense spending, Ms. Murray said “the differences between our approach and that of the House Republicans could not be starker.’’

At issue is the budget resolution — which is a nonbinding blueprint that sets spending ceilings and revenue targets for the fiscal year that begins Oct. 1 – that House and Senate must pass by April 15. If they do not, the pay for members of Congress will be withheld, under a provision of the debt-limit extension passed earlier this year.

A recent report by the Congressional Budget Office estimated that it would take $4.6 trillion in deficit reduction over 10 years for House Republicans to meet their goal of balancing the budget in a decade.

In her memo, Ms. Murray estimated that to make those cuts with out cutting defense or raising taxes, other programs would have to be cut by 23%. “The House Republicans’ extreme approach makes the need for a responsible alternative that puts middle class families first all the more clear,’’ she said.

Ms. Murray is planning to produce a budget resolution that will include both tax increases and spending cuts, but she has not said when if ever she aims to balance the budget.

The challenge for her will be to draft a budget resolution that unites the broad range of opinion among Democrats on the Budget Committee, who include socialist Bernie Sanders of Vermont and fiscally conservative Mark Warner of Virginia. Mr. Ryan’s challenge will have to persuade fellow Republicans to support spending cuts even deeper than in the past.

Mr. Ryan and House GOP leaders promised their budget resolution would show balance in 10 years, as part of a deal to persuade conservatives to support a three month extension of the debt limit. It is a tall order because even the controversial conservative budgets he drafted in the past two years, the deficit was not eliminated for another 30 years. House GOP leaders have been holding “listening sessions’’ with rank and file members to sound them out on the tough choices ahead.

But William Allison, a spokesman for the committee, said Mr. Ryan expected this year’s budget to “very much resemble’’ past budgets.

“We are not going to increase taxes, we will do tax reform and approach the entitlement crisisin a way that preserves the safety net for future generations,’’ said Mr. Allison. Although the 10-year balancing goal will require even more tough choices about cutting spending, he believed Mr. Ryan would be able to rally the party behind the plan.
